"Dream Fighter" is the 8th major single recorded by Japanese girl group Perfume for their second studio album, Triangle (2009).
It was certified gold, twice, by the Recording Industry Association of Japan (RIAJ) for physical and digital shipments of 100,000 units.
An accompanying music video was shot by Kazuaki Seki; it shows the girls performing the song in a black room, with additional computer generated imagery (CGI).
"Dream Fighter" was written, composed, arranged and produced by the Japanese musician and Capsule member Yasutaka Nakata.
Alongside the album’s remaining material, "Dream Fighter" has partial rights by Nakata through Yahama Music Communications.

[2][4] The DVD format included a limited edition flyer, where the first 100 customers who send it back to Tokuma Japan Communications before a certain date received bonus merchandise by the band.
A staff editor from CD Journal reviewed the parent album, and noted elements of electronic music.
The editor continued saying, "The vocals sound more natural because the vocoder isn’t adjusted to the levels that are similar to the previous works, the instrumental flows smoothly using mid-high tones that provide the 'dreamy' feel..."[9] The group's vocals are processed with autotune and vocoder post-production tools, which is notable throughout the group's earlier work.
[7] Martin, who also wrote about the song in The Japan Times, said that the girls vocals, "are obliterated beneath a blizzard of vocoder and an auto-tuning permafrost, all feeding into the music’s air of glacial cool..."[10] With the lyrics discussing the girls fight to make their dreams come true,[9] critics have analysed the lyrical content in their reviews.
A CD Journal staff member reviewed the parent album, and labelled the song a "refreshing listen", in comparison to the group's earlier work.
[5] A staff editor at Selective Hearing was positive in their review; they stated, "There is the familiar electro-pop sound that made everyone love them on 'Love the World' and 'Dream Fighter', so it wasn't a bad start to the album.
"[6] Ian Martin, writing for The Japan Times, was fairly positive in his review, labelling it a "pure, spine tingling pop gem".
[13] Yuki Sugioka from Hot Express was positive, commending the song's composition, Nakata's production skills, and labelled it "widely enjoyable" and "catchy".
[15] In Japan, "Dream Fighter" debuted at number two on the Oricon Singles Chart; it sold 70,873 units in its first week of sales.
[34] The song was included on their Perfume World Tour concerts in New York City, Los Angeles, Paris, London, Singapore, and South Korea.
